Suppose you were calculating a Spearman r_s on 12 pairs. In the difference column there were three zeros. You should A) include all three, leaving N = 12 B) eliminate all three, making N = 9 C) eliminate one, making N = 11.

Question

Quizplus · Accepted Answer

In Spearman's rank correlation coefficient calculation, zeros in the difference column (indicating ties) should not be eliminated. They are part of the data set, so N remains the total number of pairs, which is 12 in this case.
